Abstract
An atomizer wheel for the atomization of slurries of highly abrasive materials which includes a hub secured to a rotating shaft, a wheel bottom connected to the hub, a cylindrical side wall connected with the wheel bottom and a cover plate to form a bowl-shaped feed supply chamber. The side wall includes a number of openings fitted with bushings to provide nozzles which eject droplets of a suspension or slurry provided to the bowl-shaped feed supply chamber. The inner end of each of the bushings extend inwardly from the side wall of the wheel and the inner end or at least a portion of the inner end of at least one of the bushings extends radially inwardly from the side wall a greater distance than the inwardly extending ends of other bushings.
Claims26
An atomizer wheel for atomization of slurries comprising a hub adapted for connection to a rotating drive shaft, a bottom, a substantially cylindrical side wall and a cover plate defining an annular bowl-shaped space concentric with said hub, said side wall being formed with a plurality of openings and a plurality of nozzles formed of a wear-resistant material, each of said nozzles being inserted in one of said openings with one end projecting into said bowl-shaped space a distance from said side wall and at least one of said nozzles having at least a portion of said one end projecting into said bowl-shaped space a greater distance from said side wall than at least a portion of said one end of other ones of said nozzles.
An atomizer wheel for atomization of slurries comprising a hub adapted for connection to a rotating drive shaft, a bottom, a substantially cylindrical side wall and a cover plate defining an annular bowl-shaped space concentric with said hub, said side wall being formed with a plurality of openings and a plurality of nozzles formed of a wear resistant material, each of said nozzles being inserted in one of said openings with one end projecting into said bowl-shaped space a distance from said side wall and at least one of said nozzles having one end projecting into said bowl-shaped space a greater distance from said side wall than the other said nozzles.
An atomizer wheel for atomization of slurries comprising a hub adapted for connection to a rotating drive shaft, a bottom, a substantially cylindrical side wall and a cover plate defining an annular bowl-shaped space concentric with said hub, said side wall being formed with a plurality of openings and a plurality of nozzles formed of a wear resistant material, each of said nozzles being inserted in one of said openings with one end projecting into said bowl-shaped space a distance from said side wall and at least one of said nozzles having one end projecting into said bowl-shaped space a distance from said side wall which is less than the distance the ends of other ones of said nozzles project into said bowl-shaped space.
An atomizer wheel for atomization of slurries comprising a hub adapted for connection to a rotating drive shaft, a bottom and a substantially cylindrical side wall defining an annular bowl-shaped space concentric with said hub, said side wall being formed with a plurality of openings and a plurality of nozzles formed of a wear resistant material, each of said nozzles being inserted in one of said openings with one end projecting into said bowl-shaped space a distance from said side wall and one end of at least one of said nozzles is formed so that one part of said one end projects inward a greater distance from said side wall than another part of said one end of said nozzle.
An atomizer wheel for atomization of slurries comprising a hub adapted for connection to a rotating drive shaft, a bottom, a substantially cylindrical side wall and a cover plate defining an annular bowl-shaped space concentric with said hub, said side wall being formed with a plurality of openings arranged in at least one circular row and a plurality of nozzles including at least one element formed of a wear resistant material, each of said nozzles being inserted in one of said openings with one end of each of said elements projecting into said bowl-shaped space a distance from said side wall and alternate ones of said elements having said one end projecting into said bowl-shaped space a greater distance from said side wall than said one ends of the other said elements.
An atomizer wheel for atomization of slurries comprising a hub adapted for connection to a rotating drive shaft, a bottom, a substantially cylindrical side wall and a cover plate defining an annular bowl-shaped space concentric with said hub, said side wall being formed with a plurality of openings arranged in at least one circular row and a plurality of nozzles including at least one element formed of a wear resistant material, each of said nozzles being inserted in one of said openings with one end of each of said elements projecting into said bowl-shaped space a distance from said side wall and alternate ones of said elements have said one end formed so that one part of said one end projects inward a greater distance from said side wall than another part of said one end of said element.
